Traditional last mile delivery is known to be the most expensive leg of the journey, costing about 28% of the total delivery cost. Last mile delivery is getting the goods delivered safely to the consumers and involves interaction with the consumers. Consumers are highly likely to abandon a retailer when there are issues with their deliveries so providing a good user experience is essential in retaining them.

Last mile delivery is a major issue for businesses, especially those requiring delivery from warehouses to customers such as e-commerce. The issue is fundamental in that it deals with efficiencies in the delivery logistics itself whereby they are not done in bulk and in batches for obvious reasons. The issue has been coined "The Last Mile Problem".
